Problems solved by technology

[0003] If the existing form of blown evaporator uses the method of increasing the second-stage capillary buffer and gradual expansion to reduce the noise of the refrigerant, however, such a structure will make the length of the connecting pipe too complicated, and then when the production leads to assembly It is often unable to meet the needs of existing assembly line production, especially the existing blown evaporators have a long production process cycle, high manufacturing costs, and low product quality stability

Embodiment Construction

[0017] A production method for producing an inflatable evaporator with a composite aluminum plate, which includes the composite aluminum plate formed by cutting, annealing, roughening, printing graphite, aluminum clad plate, hot rolling and rolling, and it also includes the following steps:

[0018] a. Anneal the composite aluminum plate, the temperature is 410°C-450°C, generally 430°C, and the time is 3.5h-4.5h, generally 4h;

[0019] b. Straighten the annealed composite aluminum plate through a leveler, and then drill the process hole for blowing, and the process hole is on the graphite line;

[0020] c. Inflate through the process hole, the inflation gas is nitrogen, the air pressure is 8-10MPa, generally 9MPa, so that the aluminum plate on the graphite line is bulged to form a pipeline on the aluminum composite plate, and then the aluminum composite plate forming the pipeline is formed. to cut;

[0021] d. Punch the trimmed composite aluminum plate, punch the installation...

Abstract

The invention belongs to the field of evaporators, and in particular relates to a method for producing a roll-bond evaporator by using a composite aluminum plate. The method comprises the following steps of: annealing an aluminum plate, performing roll brushing, printing, laminating, performing hot rolling, performing roll-bond, performing powder injection, performing drying solidification and the like to form the roll-bond evaporator. The roll-bond evaporator produced by the method is high in thermal conversion efficiency and long in service life; and the method is high in production efficiency, high in automation degrees of production lines and low in cost.

Description

technical field [0001] The invention belongs to the field of evaporators, in particular to a production method for producing inflation-type evaporators with double aluminum plates. Background technique [0002] The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed gas passes through the evaporator, exchanges heat with the outside air, liquefies and absorbs heat, and achieves the cooling effect. However, as far as the existing single-door refrigerator is concerned, Since the most commonly used type is the blown evaporator, the refrigerant often produces a lot of noise when it flows. [0003] If the existing form of blown evaporator uses the method of increasing the second-stage capillary buffer and gradual expansion to reduce the noise of the refrigerant, however, such a structure will make the length of the connecting pipe too complicated, and then when the production leads to assembly It is often unable to adap...
